Start Microwave Layout In ADS 2015.1

Posted by in Hardware Design

ADS has a broad way of aspects from IC design to the RF simulation, here we explore how to prepare your workspace to start layout phase after schematic design. ADS comes with tons of ready to use parts, these parts are available at <ADS>/ADS/oalibs/componentLib/. Here I demonstrate how to add and use RF_Passive_SMT library in…


ZYNQ SD Card and RGMII Length Matching

Posted by in Hardware Design

Understanding the math behind length matching of each protocol is a key in reaching out a well designed PCB with a balance between performance and layout area and other manufacturing constraints. Unfortunately for some protocols such as SDIO these information remained under NDA’s and are confidential. Here I examined ZC702 reference design board and/or datasheet…


Export Pin Delay from Vivado into Allegro

Posted by in Hardware Design

I know that there exist many disperse app note around how to export pin delay and why you should do that nevertheless I can’t find any comprehensive guide line which accompany you from A to Z of this process so I convinced to wrote down this post. For DDR3 and other sensitive high speed signals…


In Search of the Perfect Via

Posted by in Hardware Design

Inserting via in RF and Microwave regions might seems to be a scary thing to do but as revealed through EM simulation for low portion of Microwave frequencies (below 10GHz) using a full via isn’t as worse as it seems to be. From “full via” I mean a via that start from top layer and…


Setup ADS Front to Back Design Flow

Posted by in Hardware Design

One of the great feature that comes along with ADS Package is the ability to create your design in a reverse flow. This necessity become more evident when you prefer to use other feature-reach layout tool than ADS and use ODB++ or ADFI tools afterward to import the design into the ADS for performing layout…


ADS SI/PI vs Momentum

Posted by in Hardware Design

ADS Momentum is a full-wave EM field solver that merged with ADS package for more than 10 years. Starting with the ADS 2016.1, two new tools introduced by Keysight, the SI and PI Pro environment that can be accessed through layout interface inside the ADS software. In this post, I’ll talk about features of these…


Export Allegro 17.2 Board to ADS 2017.1

Posted by in Hardware Design

Cadence and Keysight are collaborating with each other since 2000’s which brings one of unprecedented feature to reality, an ability to export your design from allegro to ADS seamlessly. In this tutorial I will demonstrate how to configure Allegro Design Flow Integration (ADFI)  for Allgero 17.2 and ADS 2017 Update 1. I am aware that…


DDR3 Length Matching – ZYNQ 7000

Posted by in Electrical Engineering

Lately DDR3 is becoming more prevalent in new custom designs however I find that there isn’t much comprehensive document available for newcomers to the DDR franchise. Here I wrote down my own bootstrap on learning DDR3 jargons and way up to design and understand underline rationale behind the DDR3 length matching. Why DDR The first…


Install ADS 2015.01 on Arch Linux

Posted by in Electrical Engineering

Advanced Design System officially support RHel 5, RHel 6 and Solaris 10. My desktop use ARCH Linux, which is not listed in the support platforms. So some steps have to taken before get ADS to work. Here I summarize my walkaround on installing ADS on Arch Linux platform which it may or may not be…
